Assessment of Carbohydrate Contents in Perlis Harumanis Mango Leaves during Vegetative and Productive Growth

Abstract

This study was aim to assess one of the flower inducing parameter of mango plant for further research and development to produce premium Perlis Harumanis mango in off-season. The carbohydrate content in mango leaves were known as the flower inducing parameter but there was no scientific research on the concentration variation of carbohydrates especially for Perlis Harumanis mango grown in the greenhouse. In this study, the elements of carbohydrate content such as glucose and starch concentration level in the leaves were analyzed using UV spectrophotometer observed during the vegetative and productive growth. The results of the study showed a higher concentration value of glucose and starch during productive growth. Meanwhile for the total carbohydrate content, the highest concentration value was obtained during the vegetative growth.
